  • Publication number: 20070232322
    Abstract: Gathering location information from a first wireless network to determine whether to anchor a communication session in a second wireless network, a mobile node capable of communicating with both the first wireless network and the second wireless network, includes receiving location information from the first wireless network as the mobile node moves through one or more service areas of the first wireless network. It is determined whether a triggering event occurs. If the triggering event occurs, the location information is stored to determine whether to anchor a session in the second wireless network.

  • Publication number: 20070201480
    Abstract: In one embodiment of the present invention, a method is provided for redirecting a session established between two endpoints. In such an embodiment, the method comprises receiving a SIP request to redirect the session to a third endpoint; dissociating the two endpoints; suspending a media session between the endpoints; connecting a signaling session between one endpoint and a third endpoint; and connecting the media session. In an alternative embodiment, a method is provided for referring a first endpoint to a second endpoint outside of an established dialog. In such an embodiment, the method comprises receiving a SIP REFER request specifying a uniform resource indicator associated with the second endpoint as a target; identifying a protocol associated with each endpoint; initiating a session with the first endpoint using an appropriate protocol; receiving media control information from the first endpoint; and connecting the session to the second endpoint using an appropriate protocol.

  • Publication number: 20070183364
    Abstract: Anchoring a communication session for a target mobile phone includes identifying a current access node operable to provide the target mobile phone access to a first network of a first network type. Potential access nodes operable to provide a mobile phone access to a second network of a second network type are identified. Whether the communication session can be handed off to a potential access node of the one or more potential access nodes is established. Anchoring of the communication session is initiated in the second network only if the communication session can be handed off to a potential access node of the one or more potential access nodes.

  • Publication number: 20060251113
    Abstract: A method is provided that includes receiving a request from a communication device to establish a communication session with a mobile station, the mobile station being operable to roam between a private and a public network. The mobile station is signaled via a cellular data network that a call is being initiated for the mobile station. Signaling information may be exchanged with a voice gateway such that one or more voice circuits are established. A signaling pathway may be established between an Internet protocol private branch exchange (IP PBX) and the mobile station via the cellular data network. The establishment of the signaling pathway is substantially concurrent with the establishment of one or more of the voice circuits. One or more features associated with a private network are delivered to the mobile station during the communication session as an end user moves between the public and private networks.
